Application filed. April 30, 1915. Serial No. 25,064.

To all whom it may concern:

Be it known that I, FELIX A. PATTEN, a subject of the King of Italy, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Belts, of which the following is a specification.

This invention relates generally to belts and particularly to that class of such devices which are round in cross section and made up of fabric.

The invention also relates to the methoc of making the same.

More specifically the invention relates to an endless belt made up of a single piece of tubing and arranged in a manner such that the ends are drawn through the side wall and into the tubing and lapped inside, thereby forming an endless belt of double thickness throughout.

The invention may be further briefly summarized as consisting in the construction and combination of parts hereinafter set forth in the following description, drawings and claim.

Referring to the drawings, Figure 1 is a view showing an elongated U-shaped loop of the tubing utilized; Fig. 2 is a view showing a portion of one leg of the U drawn through the side wall of the other leg and out at another point; Fig. 3 is a view showing a portion of each leg drawn through the wall and inside of a portion of the other leg, with the ends crossing each other and extending out through the side wall; Fig. 4 is a similar view with the ends of the fibers graduated to form the lap; and Fig. 5 is a complete view partly in section showing the finished product.

In carrying out the invention any preferred size and style of tubing may be utilized, but I prefer to use woven tubing made up of threads, and in this arrangement a suitable length is arranged, for the purpose of explanation, in the form of a U, having the curved portion 1 and the legs 2 and 3. In the making of a belt a needle is inserted to one side of the center of the curved portion 1, as shown in Fig. 2, at the point 4 through the wall of the tubing and is threaded through the leg 2 to a suitable point and then brought out at the point 5 through the wall. The end of the leg 3 is then caught with the needle and drawn through the opening 5 to the inside of the leg 2 between the opening 5 and the opening 4, and then brought out through this opening 4, so that the product atthis point is arranged substantially as shown in Fig. 2. The needle is again inserted in the curved portion 1 to the left of the opening 4:, as at 6, through the wall and through the inside of the leg 3 to a point 7 in the leg 3 corresponding to the point 5 in the leg 2. It is then brought out through the wall and is secured to the end of the leg 2, and this single portion of the leg 2 is drawn within the leg 3 and out atthe point 6, the ends of the two legs crossing inside of that portion of the tube which remains between the openings 4 and 6. The ends of the legs 2 and 3 are then frayed and the separate strands are graduated in length so that when the two ends rest one against the other inside of the curve 1 they will form no greater bulk than the single tubing utilized in the first instance. The ends before being frayed and out are drawn out of the portions of the tubing in which they are inclosed, so that when the belt is stretched and drawn, these graduated end portions will be drawn in inside into juxtaposition and will form a core for that portion of the outer part of the tubing lying between the openings 4 and 6. In this way the endless belt is formed of uniform thickness throughout, and having at all points two thicknesses of the tubing, the inner core of one leg being made by the outer casing of the other.

From the foregoing it will be seen that an endless belt is made having uniform thickness throughout and comprising an inner core and outer casing, the inner core being made up of a portion of the outer casing led in through the wall and lapped on the inside.

Having described my invention, I claim An endless band or belt, comprising a single hollow woven fabric tube each of whose opposite end portions is passed through a lateral opening in the other end portion and spaced from its extreme end a distance equal to substantially one-quarter of the total tube length, said end portions being drawn from said openings through the interior of the In testimony whereof I affix my signature tube StILLCtllI'G towardbeach otlher and nfifitin presence of two Witnesses as follows: ing or a uttin-g at sn stantial its mi e the tWo end portions forming Z core filling FELIX PATTEN' the middle body portion, and. the entire Witnesses: band being of uniform double thickness at W. S. HANNON, all points. 0 MABEL KIRK.
